PLANE.

To all whom 'it may concern.: l

Be it known that I, WILLIAM L. FISCHER, a citizen of the United States, and a resident of Oroville, in the county of Butte and State have invented new and useful Improvements in Planes, of which the following is a full, .clear and exact description.

This invention has reference to improvements in planes ofthe character ordmaril known as jack planes, the purpose of vvhic is to provide a construction ing a smooth cut extending the full width of the plane, with vthe least possible effort on the art ofthe user.

T e plane also embodies a feature of construction which makes it easy for the cutting edge of the blade to be set parallel to the: other features-of4 construe#I t1on which especially adapt the plane fori plane-base and rabbeting and 'planing floors. lReference is to be had -tothe accompanyi ing drawings forrm'n a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a central vertical longitudinal section substantially on the lline 1-1 of A Fig. 2 through f-the preferred form of my invention; Fig. 2 1s a plan of the same; Fig. 3 is a perspective view of the details of construction; and Fig. '4 is a cross-section on the line-44 of Fig, 1. l

My improved plane as preferably constructed Includes .a body composed ofv a metal base-plate 5 having the usual integral side flanges 6 and a frog 7, the latter being constructed with a recessed rear extension 7*L of reduced -W-idth, over which is slidably received a bridge-piece 8, shown in detail in Fig. 3. This bridge-piece is rabbeted at opposite edges 'on its under face to provide a ton e 9 which ts within the recess of the extended portion of the frogl and'prevents the bridge from sidewise disp acernent.

The bridge-piece is further provided with an apertured lug 10 extending rom its under face, and a longitudinal central rib 1l on Its upper face, said rib being provided with serrations adapted to engage with correspondin serrations formed on theunder face of the p ane blade 12.

The blade 12 is longitudinally slotted, as shownin Fig. 1, as is also a shoe 13 for receiving 4,the body of a guide-screw 14, the

latter operating to direct the blade lineally 's when the .bridge-piece, is adjushd; this lasti Specification of Letters Iatent. Application led September 13, 1907. Serial No. 392,804.

named adjustment being accomplished by an adjusting screw 15 threaded t into the lug 10. For holding and-"locking the blade in adjusted osition, a set-screw 16 is threaded through t e shoe 13 and presses on the blade directly over or near the serrated portion of the rib 11, thus securely re-4 taining these parts against any relative Inovement. A

As shown, receives the cutting edgev of the blade, likeJ said cutting edge is diagonally arranged and ,extends entirely across lthe base-plate, which clean cut to be taken equal width of the plane with the least possible eiort on the part of the user. This construc tion of the cutting ed ve of the blade and of the throat obviously a so makes it necessary `to laterally incline the upper face of the frog the throat 'or the plane what,

for a smooth to the entire rough the rear end of the extension 7a and. received on which the blade is seated in order that the cutting edge of the blade will be parallel to the throat and base of the plane. The two parts of the plane? body which are thus divided by the throat are rigidly connected tgether at the widened arched portion of flanges 6, the latter being provided with openings 17 into which the sides of the blade extend.

The upper portion of the plane blade, as

shown in Fig. 2, is of reduced width; which rovides shoulders 18 adapted to be brought.

Into contact with the edges of the openings 17? in setting the diagonal cutting edge of the blade parallel to the .base-plate 5; this lastnamed plate preferably having a rib19 on its upper face parallel to the throat'of the plane, w ich operates to expel the shavings as they are produced.

For working the plane I provide a knob 20 and a handle 21 which are respectively attached to the forward and rearward portions 'of the base-plate at one side thereo which especially adapts the plane for deep' rahbet- -tThe handle 21, as it will be observed from Fig. 2, also inclines toor overhanga tha; side of the plane adjacent to which it is arranged, which operates to carry the knuckles of thehand by which thehandle is grasped, sufficiently toone'side to escape contact with base-boards, etc. in planing {loors and the like. The invention as shown and described while being the preferred practical embodiment of my improved plane,V is obviously susceptible of modifications falling within .the scope of the Yclaims annexed;

Having thus'described my invention, I

5 claim as new and desire to secure by Letters"` Patent:

, 1. A plane ,comprising a body composed of a base-plate having side lianges provided with openings, a/blade projecting into said openin s having a cutting "edge, and shoulders, t e said shoulders o erating when in contact With the edges of t e o enngs to arrange said cutting edge paralle to thebaseplate, and means for advancing and retracting the blade to and from the base-plate without varying its parallelism thereto.

2. plane comprising a body composed of a base-plate having a lfrog provided with integral side flanges, vthe said frog being constructed with a rear recessed extension 'of reduced Width, a bridge-piece slidable over the recess of the extension, having a lug and a rib on its bottom and top faces, respectively,

' a slotted blade seated on the frog, a slotted shoe seated on the blade, a guide-screw passlng through the 'slots of the shoe and blade and threaded into the frog, an ladjusting screw threaded -through'the rear end of the reduced extension of the frog and connected with the lug of the bridge-piece, and a setscrew threaded through the shoe operable to force the blade into contact with the rib of the bridge-piece and lock the blade in adjustedposition.

3. A plane comprising a ,body having awhereby the blade and member will move to' gether upon the adjustment of the screw.

In testimony whereof .I havesigned my name to this specification in the presence of two subscribing witnesses.
